How many times have you attended a learning event of some kind in which you went into a room and sat down for hours? Sure you may have been engaged, and even having meaningful discussion, but I'll bet your focus wavered from time to time.
Get Your Blood Flowing, So to Speak
Most people will learn better if you force them to get up and move around the room. This doesn't mean you have to tell everyone to stand and stretch before immediately sitting back down (though you can take this approach). It can be helpful to design activities that are not only meant to draw out conversational points. Make learners, for example, move to different corners of the room that represent things they agree or disagree with. Or have them take turns volunteering to write on chart paper.
One of my favorites is to make participants draw me pictures on chart paper that relates to what I'm teaching.
Whatever you decide to try, make sure you have people move around periodically, and not just once at the beginning of the event.
